Last week i was looking for a suitable domain for a new project and found a good one. On this site i am uploading aprox a 1000 posts wich are onsite seo optimized and targeting google for 3/4 word phrases that are posted on a dripfeed base daily. Income will be generated trough aff sales. Now my question is: This domain is 10 years old and i know with aged domains that they have more credz at google IF remained on the same host. It has moved in that time from 5 hosts to another and now obviously on mine. Do i still have some authority?
